Intel's Ivy Bridge chip architecture may have its launch timing narrowed down based on an updated roadmap leaked out Wednesday. Where a previous copy had only given the 22 nanometer desktop processors a vague first-half 2011 target, MyDrivers' new version narrowed the release down to a "March-April" timeframe. The schedule wasn't strictly a delay but would be later than Intel's usual tendency to have shipping designs ready in or near January.
